| Unpredictable climatic conditions and increasing pressure on non-renewable resources mean that alternative agricultural systems able to cope with increasing biotic and abiotic stresses, as well as external input costs, are needed. Sustainable agricultural systems should be self-regulating, characterized by a high degree of interand intra-specific diversity (Moreau 2010). Evolutionary breeding through the introduction of Composite Cross Populations (CCPs) increases intra-specific diversity, enabling CCPs to adapt to changing environmental conditions. Increasing interspecific diversity, through mixed cropping, also plays an important role in sustainable systems and suitable crops are needed that are able to cope with the increasing interspecific competition... |

| Evolutionary breeding through the introduction of composite cross populations (CCPs)encourages intra-specific diversity and increases diversity in the agricultural landscape. Increased genetic diversity in crops may help to buffer both biotic and abiotic stresses and will play an increasingly important role in unpredictable climatic conditions become more unpredictable (Østergård et al. 2009). A number of CC winter wheat populations, commercial varieties and CCP line selections were tested at the University of Kassel, under differing N input levels in order to test past adaptation and suitability to differing fertilisation levels. The CCPs have been managed since 2005 under both organic and conventional conditions without conscious selection. Genetically... |
